… about researchers sharing participant data for reuse?
17 February 2025
Do participants read
informed consent forms?
Dwell time on consent: Reading speed (as words per minute):
Additional coding
Do participants read
informed consent forms?
replication part
expansion part
“Will the data be shared after the project is completed?”
No, all data will be deleted.
Yes, data will be shared with researchers.
Yes, data will be shared with the public.
Yes, data will be shared via the University’s secured website.
Yes, data will be shared via a trustworthy archive.
Taking into account prior knowledge regarding research data handling
Structural model only (without measurement models)
Trouble with dwell_time being skewed? -> log-transform?
# Define the SEM model
model <- "
# MEASUREMENT MODELS
knowledge =~ knowledge1 +
knowledge2 +
knowledge3 +
knowledge4
read_engagement =~ read_engagement1 +
read_engagement2 +
read_engagement3 +
read_engagement4
understanding =~ understanding1 +
understanding2 +
understanding3 +
understanding4
# REGRESSIONS
dwell_time ~ knowledge
read_engagement ~ knowledge
understanding ~ knowledge
# COVARIANCES
dwell_time ~~ read_engagement
dwell_time ~~ understanding
understanding ~~ read_engagement

fit <- lavaan::sem(fit, data = data)
summary(fit, standardized = TRUE, fit.measures = TRUE)
Does the information on sharing data influence the participants’ willingness to participate?
(for different data types?)

perceived_sensitivity as control
Does the option to clarify concerns about the informed consent make a difference in the willingness to participate?
What does CG do?
Or just measure CG once and paste values to posttest? (-> statistically dependent)
Structural model only (without measurement models)
General: Idea for a journal? -> registered report?
Study 1: How to ideally collect log-data from past online surveys -> ask in LLiB?
Study 2: How to collect participants? Panel provider probably biased
Study 2: What if participants don’t read the fictitious example? -> ecological validity? internal validity?
